WIRE-BOPE-SIECUEING MEANS.

Application filed September 22, 1920.

T aZZ whom may concern:

Be it known that I, \VILLIAM Gonrz, citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia Canada, have invented certain new and useful improvements in Wire- Ropefiecuring Means, of which the following is a specification.

This invention relates to a wire rope securing means which has been particularly designed to enable a wire rope guy or the like to be tightened in its connection to its anchorage, and for securing it in that tightened condition.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Fig. 1 is a side elevation of the device as connected to tighten a rope, the full lines showing it in the position as when ti, itening, andthe dot and dash lines as when the tightening is effected and the device secured.

Fig. 2 is a plan of the same.

Fig. 3 an end elevation looking in the direction of the arrow 3, and

4; is a cross section to an enlarged scale on the line 1 -4 in Fig. 1.

In these drawings 2 represents a Wire rope guy line which it is required to tighten in its connection to its anchorage. This wire rope is passed around a grooved sheave 4 which is rotatably mounted between side frames between which frames a shackle or eye 6 is mounted by which the device is connected to its anchorage preferably by means of a releasable hook. such as is the subject of a co-pending application.

The guy rope 2 is taken over the upper side of the she-awe and passes from the unde de as at 3, between the jaws of a clamp 7. 8 to the donkey engine or other power means by which the guy rope 2 is to be tightened.

The upper clamp member 7 is integral with or secured between the side "frame plates and the lower member 8 is pivoted at 9 to lugs projecting downward from the side plates adjacent the sheave 1-. @ne of these clamp members has a convex projec tion 10 which fits a corresponding concavity in the other clamp member, and the adjacent parts or both clamp members are longitudinally grooved to receive the rope, so that the rope on being clamped is bent Serial N0. 412,079.

around the projection 10 and a better grip is thereby obtained of the rope.

The slack end 3 of the rope is retained alongside that portion 7 of the clamp member which is integral with the side frames in which the sheave et is mounted, by a fair lead sheave connected by links 16 to a pin 17 across the end of the clamp 7, which end is enlarged, as at 18, to retain it.

The lower clamp member 8 is drawn up to 7 to clamp the rope between them by bolts 11 pivotally connected to lugs projecting from each side of 8. which bolts pass between corresponding lugs 13 projecting from the clamp member 7.

The sheave i is provided with ratchet teeth 19 on one or both sides of the groove, which teeth are engaged by a paw-l 20 mounted in the frame 5 and prevents the sheave rotating backward. By thus securing the sheave against rotation backwarn, the frictional hold of the rope around he half circumference of the sheave will re- L lieve the strain imposed on the clamp.

in use the shackle 6 being connected to the anchorage. and the guy rope 2 passed around the sheave land between the clamp members 7 and 8 over the sheave l5, tension y be imposed on the end 3 of the rope to en the guy rope 2. When the desired tension has been imposed on the rope the bolts 11. are upwardly turned to engage the i and the clamp member 8 is drawn itly toward 7 to secure the rope bet-ween h em in its tightened condition. When this s accomplished the fair lead sheave 15 may be removed and the end 3 of the rope re leased from connection to the donkey or other tightening mechanism. The device will then assume the position indicated by the dot and dash lines in Fig. 1..

It will be noted that the connection 6 of the device to the anchorage is offset from the line of the clamp 7., 8 so that when the rope J. L i

Having now particularly described my invention, l7 herclrv declare that what I: claim as nev: and desire to be protected in by Letters Patent is:

l. liiieans for securing a Wire "i'opeto its anchorage, said means com n-ising in combination, a grooved sheave adapted to take the wire rope to be tightened. side frames between which the sheave is rotatably mounted, a wire rope clan'ip secured to the frame'on one side of the sheave, means preventing backward rotation oi. the sheave from the clamp, means connected to the side frames on the other side ot the sheave for connecting the Frames to an aiichorage and a fair lead sheave removably mounted on said irame adjacent to said clamp.

2. Means for securing a wire rope to its anchorage, said means comprising in combination, a grooved sheave adapted to receive the wire rope to be tightened, side frames between which the sheave is rotatably 'inounted, which side frames are extended tangentially from one side of the sheave and have a wire rope clamp between them, means preventing rotation of the sheave backward From the clamp, and means offset from the line of the clamp For connecting the side frames to the anchorage.

3. Mains tor securing a wire rope to its anchorage, said means comprising; a grooved sheave adapted to receive the rope to be tightened, said sheave havingratchet teeth adjacent its periphery preventing backward movement of the sheave, side frames between which the sheave is rotatab v inv-mnteih which frames are extended tangentially from one side of the sheavea fixed clamp member between the'tangentially extended portions of the side plates grooved to receive the wire rope, a fair lead remov'ablv connected to the end. oi the tangentially projecting portion of the side frames and adapted to retain the wire rope parallel to the clamp member, a movable clamp member pin-connected to the side frames adjacent the sheave, the free end of which clamp member is extended toward the tangentially projecting portion of the t'i'anie, said clamp member grooved to receive the rope, bolts pivotaliy connected to one clamp member, lugs on each side of the otherclamp me her adapted to receive the bolts and enable them to tighten one clamp member on the other, a pavvl mounted on the side frames to engage the ratchet teeth of the sheave and a shackle pivotaltv mounted between the side frames on the opposite side of the sheave from the clamp for connection oi. the device to an anchorage.

a. Means for securing a wire rope to its anchorage, said means comprising in coming saidclamping member toward the said GtlQG- face of the frame to clamp the slack end of the rope, andmeans preventing backward rotation of the sheave from the clamp,

said frame having" a portion provided with means to connect to an anchorage, said means being offset from the line of said clamping edge of the frame.

5. Means for securing a wire rope to its anchorage, said means comprising in combination, agrooved sheave adapted to take the wire rope to be tightened, a frame recessed to receive said sheave in which recess said sheave is rotatably mounted, a wire rope clamping member pivot-ally secured to one ec ge face of the frame, means for drawing said clamping member toward the said edge face of the frame to clamp the slack end of the rope, means preventing baclr ward rotation o'l the sheave from the clamp, and a rope guide on one end of the frame over which the slack end of the rope passes t'or aligning the slack end of the rope with the sheave and clamp.

(3. lrleani-i For securing a wire YOPQ to its anchorage said means comprising; a grooved sheave ada ited to receive the wire rope to be tigl'itened a frame having; side members between which said sheave is rotatablv mounted, said frame being extended with a face tangential to the perigherv of said sheave, along which face the slack end oi the rope lies, a movable clamp member can ried by said frame and adapted to grip the slack end of the rope against the tangential face oil the fran'ie, a ratchet and pawl connection between said frame and sheave to prevent bacrward rotation of said sheave, and a guide sheave u'iounted on said frame over which the slack end of the cable passes for holding; the slack end of the cable in alignment with the first mentioned sheave and clamp.
